Cisco Firewall :: Assign Several IP Addresses To External Interface ASA 5510?

Oct 13, 2011

How do i tell my firewall to start listen also on another outside ipadress assigned by my ISP? I have it used on other firewall right now. So my steps would be shutting down ip address assignment off old firewall interface. Assign that ip address to ASA5510 outside interface and configure NAT.

Cisco Firewall :: ASA 5510 - How To Assign Multiple Public IP Addresses

Dec 2, 2010

I'm currently replacing my ASA 5505 with a 5510. I have a range of public IP addresses, one has been assigned to the outside interface by the setup wizard (e.g. 123.123.123.124 ) and another I would like to NAT to an internal server (e.g 192.168.0.3 > 123.123.123.125). On my asa 5505 this seemed fairly straigh forward, i.e. create an incoming access rule that allowed SMTP to 123.123.123.125 and then create a static nat to translate 192.168.0.3 to 123.123.123.125. Since I've tried to do the same on the 5510 traffic is not passing through so I'm assuming that the use of additional public IP addresses is not handled in the same way as the 5505? I also see that by default on the 5505, 2 VLANs are created, one for the inside and one for the outside, where as this is not the case on the 5510. Is the problem that VLANs or sub-interfaces need to be created first?  I'm doing the config via ASDM.
 
Everything else seems to OK i.e. access to ASDM via 123.123.123.124, outbound PAT and the site-to-site VPN.

Cisco Firewall :: ASA 5510 - Two External Subnets On The Same Interface

Oct 21, 2012

I have two ASA 5510 in an active-standby cluster, not that I think that the fact that they are clustered will be of any importance here so feel free to think of it as a single 5510. The internet connection is delivered in a single RJ45 connection. To be able to use it with the cluster there is a simple unmanaged switch connected between the ISP and the ASA's. I have two subnets with public addresses, for simplicity lets call them 1.1.1.0/24 and 2.2.2.0/24. Default routers are 1.1.1.1 and 2.2.2.1 respectively.
 
Can I somehow use both these subnets in the ASA's? Im currently using the first subnet and use PAT to direct traffic to internal servers. But if I want to use adresses from the second subnet wont that mess up the routing, since there is no way I can specify the default router for the second subnet? I have as of yet not tried anything, Im just trying to plan ahead and I cant seem to wrap my head around how this could possibly be done.

Cisco Firewall :: Pix 515E Cannot Ping Or Assign DHCP Addresses To Inside Clients

May 6, 2011

I have a PIX 515E that I want to use to as a border between my internet connection and my Cisco AIR1131AG.  I have configured the PIX to have the outside interface as a dhcp client which gets its dynamic IP address from the cable modem. the AP is connected to the E1 inside interface. Now I could see the E1 interface from the arp table from the AP but I cannot ping it. From the firewall I don't see the ARP  table  from the firewall. and i cannot ping the AP. what is wrong with the configuration? side note, i am able to connect to the AIR1131AG from my laptop I was not able to retrieve an IP address.

Cisco VPN :: ASA 5510 / VPN Behind Another External Interface

Dec 23, 2012

i have an ASA 5510 My ISP provides for me 2 separate public networks. One is routable from outside of the world and one is not (and is used as a gateway for the THAT routable network)

Assume that non routable network is a.a.a.a and routable is b.b.b.b so we have 2 interfaces on asa - a.a.a.1 and b.b.b.1 Physically this  network b.b.b.b is behind network a.a.a.a one cable comes to me and plugged to ASA As i said all traffic from/to external(routable) network is going through network a.a.a.a (and a default gateway at ISP) So the problem:For my international partners i need to provide  VPN.So the traffic flow is the following:for exaple a client with public ip 1.1.1.1 using cisco VPN client trying to connect to b.b.b.1 The packet arrives to interface a.a.a.1 and............. Being  discarded.7Dec 24 201211:09:477100051.1.1.162548b.b.b.110000TCP request discarded from 1.1.1.1/62548 to internet:b.b.b.1/10000 I assume that the ASA discards the packet BECAUSE IT COMES FROM a WRONG interface.Am i right?Also i tried to setup a bypas policy, but no effect?

Cisco Routers :: RV042 Firewall Multiple External IP Addresses

Oct 6, 2011

if possible with the RV042.Primary External IP address uses port forwards for some ports, all okay.I would like to have other external ip addresses assigned to machines on my lan.Basic host multiple web servers, on different IP addresses, using port 80. [code]
 
From what i am reading, it looks like the RV042 can do this, but I am not real clear what my rules should look like.
 
I would think my high priority rule for each external IP address would be to deny all traffic first for each machine on the lan.Then create one entry with source 202.x.x.2 port 80 -> 192.168.168.2 ?
 
How should I set my rules to do this, and what settings should I have on the Nic of the second machine?

Cisco Firewall :: Possible For 5505 To Route / Map Renaming Private IP Addresses Through Its External Port

Jul 25, 2011

I have purchased a subnet of 8 private IP addresses from my ISP. 109.x.x.128/29.The ISP has placed a juniper router within our data centre which is routing purely from 109.x.x.206/30 to 109.x.x.128/29 with the ip of fa0/1 set to .129.
 
I have linked a cisco 5505 to fa0/1 of the juniper from fa0/0 and configured its IP to .130. I have configured NAT to translate our client pool 192.168.16.x /24 address' to the internet.
 
Is it possible for the 5505 to route / map my remaing private IP addresses through its external port? I have tried creating a seperate VLAN for a DMZ for our servers to sit within but am returned with a subnetting error as VLAN for my external port is all ready configured within the same subnet.

Cisco WAN :: 2821 How To Assign For A Port One / More Public Addresses

Nov 2, 2011

I just thought if it's possible to make sure that only approved IP addresses for each of divisions of a company can be used.How can I assign for a port one/more public addresses and be sure that only this port is using it/them. Thing is I have only one 24 bit public Network ID provided to me by ISP. One IP address of the range is used for ISP's gateway. So I have 253 addresses to be distributed among divisions. However to avoid IP address conflicts I have to be sure that only dedicated for a division IP address/es is/are used by the division.
 
Router is 2821.
Switch is 2950.

Cisco Firewall :: ISP Migration With ASA 5510 And External Router?

Nov 26, 2012

My company (in Healthcare) is going to be changing ISPs for our internet connectivity, and with this change comes a new external IP block.  So I need a scheme to migrate over all of my existing VPN tunnels and other items over to new IP addresses.  We do have an external router which I plan on doing a route-map to handle which traffic the ISP should go to based on IP.  My big concern is for the ASA 5510.  Can I setup a second outside interface on the new IP range?  Then migrate my VPN tunnels over one-by-one?  A drop-dead cutover date is just not possible with all of the external companies that I have to contact to get VPN tunnels updated with.  If it's not possible, we have in our budget to get another 5510 next year as a redundant unit.  I may be able to get that early and just migrate from one firewall to another.

Cisco Firewall :: 5510 - Can’t Access External IP From Within LAN

Oct 20, 2010

Basically we have different customers using the same 5510 firewall. We have created one sub interface for every customer on the inside interface. There are differed NAT rules for every customer all using the same block of public IP addresses on the outside interface. They do not have access to each other’s network so I cannot make any exemption rules between two sub interfaces. The problem is for all our customers that they cannot communicate with each other over Internet, Email, Applications etc. using the external IP address. A work around is to use a proxy server, but they do not agree with that. I cannot make exemption rules between sub interfaces for security reasons.

Cisco Firewall :: 5510 - How To Allow Access From LAN To Server Using External FQDN

Feb 20, 2012

I may have phrased the topic not too clearly, but I have an external domain name of mail.company.com , I want my users INSIDE the company be able to also get to url..., currently they cannot (nothing loads, looks to me as if firewall simply drops it) and I'm drawing a blank on how to get this done. Externally this works fine so if you're outside the company you can load up OWA just fine since my NAT rule translates the external IP to internal IP, but something is blocking this from the inside.
 
I have an ASA 5510. If you can just sent me on the right path with theory I'll figure it out on my own, I don't need exact steps, but I must be thinking of this wrong as I'm not getting anywhere.

Cisco WAN :: ASA 5505 - Assign External IP To Internal Server?

The first one I use to provide internet access to my office.

External ips must be assigned to servers' interfacw,bot just forwarded there (ms direct access requirement).

Cisco Switches :: SG500 DHCP Server Does Not Assign Predefined Static IP Addresses

I tried with hardware address and client identifiers. no luck. my switch does not assign the IP address I assigned to the suitable mac address. to define it I use both CLI & Web.

Cisco Firewall :: Statically PAT Multiple Internal Hosts To One External Host 5510

Feb 20, 2012

I am working on replacing our Checkpoint Firewalls with ASA's, and am running into the following NAT problem. On some of our Checkpoints, there are external NAT's that are mapped to multiple internal hosts based on ports.Is there any way to translate that to the ASA? I'm not sure the ASA will let you have multiple internal hosts mapped to one external IP using static NATs. The main issue, is these are alarm panels that receive data from external hosts (the traffic is initiated externally on the Internet) so I can't use dynamic PAT with this.

Cisco Firewall :: 5510 Security Plus To Terminate Client VPN Access For External Support Team

Aug 7, 2012

I have a customer that wants to purchase an ASA 5510 security plus to terminate client VPN access for an external support team. The customer claims to want URL content filtering/proxy which leads me to suggest a CSC SSM 20 plus module. But upon further conversation, he mentioned wanting IPS. In this case, the customer does not seem to know the difference between the URL content filter/proxy and the IPS and uses both terms interchangably.
 
1. What would you suggest in your expert opinion would be the best module to get for this customer? IPS or CSC
 
2. If I go with the CSC module, where can I find good documentation on how to configure it and get it up to date?
 
3. does the CSC module provide any web proxy functionality?
